Construction plans of dry dams that allow riverbed materials to flow downstream have been increased, while preventing the water level from rising at normal times by installing outlet works near the elevation of the riverbed with a view to conserving the river environment. This paper summarizes the rationalization of curtain grouting based on analysis using documents of 78 dams that carried out first impounding after the 2003 revision of the Grouting Guidelines in Japan, and reviews the characteristics of curtain grouting rationalization. Of the dams surveyed, those with relatively large leakages during first impounding were extracted, the causes of leakages were analyzed, and the conditions to be noted in the rationalization of curtain grouting were studied.
